New nVidia drivers for Lion

gtx580 support out of the box –

and just one string i found in gldriver – KeplerDecisionMaker (has also FermiDecisionMaker)

Far less than what we see for tahiti in amd drivers tho.

But main thing about this driver is ability to work without injector/graphicsEnabler (thx to our forum members for figuring it out) , and its fine for dual-dvi cards.

So nVidia cards works without efi rom or aty_init on macpros now, just plug it in, just no boot screen.

    Just plugged in a MSI Twin Forzr III GTX 570 and it works so far, no fan problems. I do have an issue where either upon boot or when waking from sleep, one of the DVI outputs will only show digital “snow” for about 20 seconds, then it kicks in and starts working properly. Seems like the Mac has to “find and see” the second DVI port and enable it before video appears, but it does work on both ports. Spent 30 minutes playing Borderlands; it’s the smoothest it’s ever been on the Mac (but it still plays smoother on Windows).

    Hope This Helps You Sir

    The Ultimate PC Tune Up Guide

    Do a backup.

    First do a backup. Whether we want to admit it or not, all hard drives fail, and furthermore, hard drives never crash at a convenient time. So before we start doing anything, let’s back up your hard drive. I use an external hard drive connected to a USB2 port and I try to back up at least once a month. I only back up my critical data, which is essentially the My Documents directory and my email folders. The entire process takes about half an hour.

    Delete your junk mail folder.

    Did you know that junk mail slows down system performance? Every time you receive an email (good or bad), that email is written to your hard drive. Not such a big deal, but 90% of the email that I receive is actually spam, and it just eats up hard drive space, and further fragments my hard drive. Usually before deleting my junk mail folder, I try to take a quick skim to see if it accidentally classified a good email as bad (the dreaded false positive). In the course of a month, I usually find about 1-2 good emails marked as spam.

    Empty the recycle bin.

    When you delete a file, it really is still on your hard drive in the recycle bin, out of sight, out of mind. Although it is handy to be able to find an accidentally deleted file, over time, gigabytes and gigabytes of junk accumulate and should be erased . Note: this also poses a security risk because it makes it easy for people to find the things you really wanted permanently deleted. At PC Pitstop, we have seen systems with more than 50GB’s sitting in the Recycle Bin.

    Clear out temporary system files.

    What happens when you open an attachment from your favorite email client, or when Word is doing an auto save on your new novel? All of your data and much more is being stored in temporary system files throughout your hard drive. Just like your recycle bin, it can be handy, but over the course of days and weeks, it only serves to clog up your hard drive. You should reclaim all of that space, and sometimes it can be a lot!

    Clear out internet cache.

    Whether your browser is FireFox or Internet Explorer, both have an internet cache with tons of information about each and every web site you visit. In the short term, these caches speed up web browsing, but over the medium term, if you browse the web a lot (who doesn’t?), then these caches get big and unwieldy. At PC Pitstop, we actually have seen more than one PC with an internet cache of more than 100GB.

    Uninstall any unused programs.

    It has happened to all of us, we download 4-5 software applications, looking for a solution to a particular problem. That’s great, but your hard drive now has quite a few applications that you never intend to use. Or perhaps, you downloaded/bought something a long time ago, but you no longer have a use for it. If this is the case, then uninstall any and all programs that you no longer have a use for. There are three big reasons why you should uninstall programs you don’t use. 1) Programs take up hard drive space, 2) Many programs install background processes that use up processor cycles and memory even if you are not using them, and 3) All programs create entries into your Windows Registry. By uninstalling unwanted programs, you are also uninstalling unwanted registry entries.

    My experience:

    *I use my machine for Cuda rendering 3D only (no gaming), so I need the maximum Cuda power.
    *I used an additional PSU to feed the GTX580 cards.


    1.- Mac Pro 3.1 early 2008 + Radeon HD 2600 + GTX 285 + GTX 580
    *Works nice with “Octane Render” (2 GPUS) also with “Blender” (but only one GPU).

    2.- Mac Pro 3.1 early 2008 + Radeon HD 2600 + GTX 580 + GTX 580
    “Octane Render” works (2 GPUs) also with works “Blender” (2 GPUs).
    *Works, yes, but OSX crash after a minute or less if I try to render something (aka: stress the cards).

    To bad 🙁
    The performance is awesome with two 580 at once, I hope someone find a workaround to get rid of the crash.

    Ok, I found a workaround so now I’ve: 2 x GTX580 + 1 GTX 285 at once. I’m happy now

    GTX285 = PCIe 1 (16x)
    GTX580 = PCIe 2 (16x)
    GTX580 = PCIe 4 (4x)

    Only a couple of bad things:
    I lost several HardDisk bays (because the uppermost card occupies the space).
    One GTX580 is on a 4x PCIe slot (Don’t worry, only affects time of scene uploading, rendering is fine.

    Despite that few things, the results are pretty AWESOME, really a new life to an old computer like that.

    P.D: Notice I haven’t hacked nothing, so you can use a standard GTX580 (no need Mac version), the only you need is the new drivers for OSX Lion from NVidia and possibly (like in my case) an external power supply.

    Hey Guys,

    So after reading this post I have bought a “1GB EVGA GTX 560 Ti SC” and “2x mini 6pin to regular 6pin power cables”.

    I have an early 2008 mac pro running the latest lion build and have never had any flashed cards in there before.

    I hope i’m right in saying I should just be able to install the new drivers and install the card and away I go?

    Have I missed anything?

    P.S. Im assuming to run this system on my boot camp partition I will just need to install the standard windows nvidia drivers for this card?

    Any feedback would be much appreciated.

    Any experiences if this also applies to GTX680? For I’m going to switch from FCP7 to Premiere I’m looking for a CUDA card for my Mac Pro (mid 2010), and deciding between GTX570, GTX580 und GTX680 the latter seems like the best choice…

    Anyone tried this with the 10.7.4 update?
    My GTX580 is working perfectly on 10.7.3 at the moment.

    I can confirm, that the ‘EVGA 570 GTX SuperClocked’ work like a charm in my 2009 Mac Pro.

    I ran UNiGiNE Heaven 3.0, with these settings, and got these scores:


    Heaven Benchmark v3.0 Basic

    FPS: 45.3
    Scores: 1142
    Min FPS: 15.1
    Max FPS: 75.4

    CPU model: Intel(R) Xeon(R) CPU E5520 @ 2.27GHz
    CPU flags: 2260MHz MMX SSE SSE2 SSE3 SSSE3 SSE41 SSE42 HTT
    GPU model: NVIDIA GeForce GTX 570NVIDIA GeForce GT 120 512Mb

    Render: opengl
    Mode: 1920×1200 8xAA fullscreen
    Shaders: high

    Filter: trilinear
    Anisotropy: 16x
    Occlusion: enabled
    Refraction: enabled
    Volumetric: enabled
    Tessellation: disabled


    For comparison, i ran it on my nvidia GT 120 card as well. Same settings, except lower screen resolution: 1280×1024
    Here’s the scores:

    FPS: 6.6
    Scores: 167
    Min FPS: 4.1
    Max FPS: 14.5


    I grab the PCIe power from both outlets on the motherboard.

    Thumbs up.

    Je veux savoir si quelqu’un a réussi a installer la GTX 690 sur mac pro, si oui ça donne quoi sur adobe première pro 5.5 et photoschop? car moi j’ai essayé la gtx 480, elle super mais marche uniquement sur windows 7, elle chauffe un peu il me semble, j’ai acheté un cable 6 pin vers 8 pin des usa et sa marché, je peux travailler en temps réel, mais elle m’as laché au bout de 3 mois, je pense à moins que je me trompe à case du manque de l’alim et pourtant mac pro, il as 950w, heureusement j’ai la garantie, merci de ce forum, mac c’est bien mais il nous emmerdent afin de ne pas être à jour comme un PC. pardon une question quelqu’un a essayé de travailler en Raid 0 en boutant sur Windows 7 avec la carte RocketRaid 2302? merci bc et je vous prie d’agérer mes meilleures salutations.

    Hello! I first would like to thanks Netkas and all the community for this awesome work…

    @Mike & Doug
    I have exactly the same issue as you. I tried to put a Leadtek GTX 580 3Go in my MP 3,1, the card worked perfectly, but the fan was not working, so, same thing as you, in 3 minutes the card shutted down. I thought the card had a problem, I changed it for a Zotac, 3Go, yesterday. Exactly same problem. Alimented from the superdrive Molex to 6 Pin, and from the 2 connectors from the motherboard to 8 pin. The card passes all the tests in OpenGl extension viewer. The fan just tried to run on startup, but never run. Tried 10.7.3 and 10.7.4 drivers from nvidia, after os update. Even tried to remove all the HDD, except the SSD in secondary 5,25. No changes.
    If anyone would have an idea… could be so great!
    Thanks a lot!

    GTX 580 not working 🙁

    Got a Mac 3,1 (early 2008) with Lion 10.7.4
    Installed the latest drivers from NVidia web page, for Lion 10.7.4

    When I install the card, I get a black screen.
    If I use another card in parallel (GT 120), I can login but on About This Mac I only see my regular GT 120 installed.
    If I leave only the GTX 580 and use VNC to remote manage the mac, I see no video cards detected

    Should I do something else to get the GTX 580 working?

    In my case, I installed a GTX 580 classified ultra in my mac pro 09.

    it is working, but whenever i load intensive graphic (playing game/ 3d rendering), my towner shut off and re-boot.

    do you guys know what is going on? (not enough power i guess), i draw power from the internal molex which converted from SATAs for 1 x 6pin & 1 x 8pin, for the other 8 pin connector, I draw power from the 2 x 6 pin slot to a 8 pin on the motherboard. i don’t understand, the 980 PSU seems like is good enough to power up the GPU, but its not.

    now, I just bought an external 650w PSU just for the GPU, hope this work!

    also, is there anyway to enable efi boot? the towner always go all the way to lion, whenever i need windows, i have to unplug the lion drive from the computer in order to get it work. it is weird that the target drive function won’t recognize my windows 7 partition.

    I just made a clean install of Mac OS X mountain lion 10.8 and my geforce gtx580 Palit 3072 is natively recognized (on a macpro 2009). No need to install anything else.
